This Digital Thermal probe/sensor DS18B20 is a rugged beast, it's epoxy encapsulated within a stainless steel tube and ready to brave the elements.
This digital thermal probe employs the DALLAS semiconductor 18B20. It's unique 1-wire interface makes it easy to communicate with devices as it doesn't require any external power supply since it draws power from data line. It can convert temperature to a 12-bit digital word in 750ms (max). Besides that, it can measure temperatures from –55°C to +125°C (–67°F to +257°F). Last but not least, like other common thermal probes, its stainless steel enclosure makes it suitable for any wet or harsh environment.
